2 Claims.

This invention relates to light sockets and in particular aims to provide a novel socket adapted to be quickly attached to wires forming part of an energizing circuit for the lamp.

An object of my invention is to provide a socket into which may be inserted bared or stripped sections of wires to constitute the feed and return leads for the circuit to be connected to the socket, and with the arrangement such that the wires will be securely held in the socket and at the same time prevented from coming into contact with each other to cause a short circuit.

A feature of the invention is a socket made from electrical insulating or dielectric material, and thus made by molding a plastic; the socket having openings through which the bared ends of the wires may be quickly inserted so that when the light bulb is threaded into place the metallic base of the latter will complete the circuit between the wires to light the bulb. Among other features are an attaching means for mounting the socket on any supporting surface, and automatic locking means for the bared portions of the wires whereby they will be securely held in the socket to eliminate any danger of short circuiting.

For further comprehension of the invention,

and of the objects and advantages thereof, reference will b had to the following description and accompanying drawings, and to the. appended claims in which the various novel features of the invention are more particularly set forth.

Referring to the drawings in detail, and particularly to the form of the inventionshown in Figs. 1-5 In indicates an electric bulb socket body, made say from a dielectric plastic material by molding, and having a recess II interiorly threaded at I2 to receive the threaded metal sheath I3 of a light bulb plug I 4 from whose end projects the contact stud I5, the bulb itself being indicated at I6. In order that the circuit between the stud I5 and sheath I3 may be completed to light the lamp, the parts I3 and I5 contact the bared portions I1 and I8 respectively of the wires I9 that constitute the feed and return sides of a circuit. The socket comprises a cap or wire holder 20 having a recess 2I into which fits the lower end of the socket II], the latter having an annular bead 22 which engages a groove 23 formed in the rim 24 of said cap to hold the socket and cap assembled with a frictional fit, but permitting ready detachment of the parts. The cap is provided with two molded or inserted blades 25 and 26 which are aligned with transverse grooves 21 and 28 respectively, in the latter of which .the wires I9 seat so that their bared portions I! and I8 rest on the blades 25 and 26 respectively. When the cap is placed over the end of thesocket as in Fig. 4, the blades 25 and 26 and the wires supported thereon are thrust into slots 29 and 30 of the plug.

The blade 25, being longer'than blade 26, will fit into the deep slot 29 in the socket'to position the wire I! so that it is tangent to'a portion of the thread I2 where the latter is interrupted by an aperture 3I opening into the cavity I'I. Likewise the wire I8 on top of blade 26 will enter the shallower slot 30 and project through an aperture 33 formed in the bottom of the cavity I I and opening into the slot 30. When the light bulb is threaded into the socket the button or stud I5 thereof will engage Wire I8 and the threaded sheath I3 will engage wire I! to form a circuit through the lamp I6, as shown in Fig. 3.

Referring to the form of the invention shown in Figs. 6 to 10, 35 indicates a socket body which is preferably made by molding a dielectric plastic to provide a threaded cavity 36, the threads of which terminate short of the bottom of the cavity as at 31, so that the metallic base I3 of the electric light bulb I6 when threaded into the socket will be limited in its threaded movement for a purpose to be hereafter described.

The socket is of any desired shape and may be cast to provide a holding means 40 in the nature of a lug through the medium of which it may be attached to a supporting surface, as by a screw 4|. The socket may be molded or drilled to provide adjacent the bottom thereof bores or 3 openings into which may be inserted the stripped ends of a pair of wires 43 and 44.

The socket is apertured diametrally at 42, for receiving the bared portion of the wire 4.3, and is apertured :at 45 at one sidefito .provide axbore in which the bared portion of wire 44 is received, the bore 45 being tangent to the threads of the cavity 36, so that the wire M will be engaged by the thread of the metallic base ['3 of the light;

bulb when the latter is screwed intothe socket. When the bulb has been completely threaded into the socket the bottom of the acenterntudfi of the bulb plug will engage the wire 43. to thus form a circuit in the usual manner through "the wires and the light bulb.

In- Fig. =9, I have shown, -in lieu of the bore MS of Figs. 7 and8, a bore 4 formed at an-angle to the horizontal to-correspond to the pitch :oI-the threads 'of the'sooketso that whenthe wire .is inserted into the bore '41, it wil1 rest in the :bottom of the particular thread with which it aligned and when the bulb is secured into the socket z-it will =eiIective'ly pull -on-'-the wire and :hold :it against accidental removal. But it should be noted that locking of the wiresoccurs also in 1 the invention=illustratedin Fig. '7, because -as the metallic base of the light bulb is threaded into position, it jams-ibetweenthe wires -13 and and causes the latter to 'be slightly "bent and held in the socket against accidental withdrawal.

The outstanding advantages of the sooketzdescribed are its simplicity of assembly, saving :of space and elimination 1 of many of the parts used in the manufacture of sockets at the present time. It decreases the overall costof manuiac- 'ture, decreases labor costs, and therefore :increases production. -In addition it "is completely waterproof, 'and eliminates the possibility: 20f short circuits-and of any of its parts becoming ioosemrcorrosive.

While -I have illustratedanddescribed the .pre- Ierroi'l embodiments of my invention, it is :to :he understood that I .6.0 311015 limit "myself etc :the precise rconstructions iherein-zdisclosed and stile erightlis reserved 'tozallchanges and modification coming within-the; scope of the invention 11 5:21 inneddn-therappended :igclaims.

,Having thus :described any invention, what :1 claim as new, and-desire ,to secure by United states Letters Patent :13:
